[Resolved]  HTC One X — service repair

i have sent my HTC X One to Technocare within the warranty period to be repaired, as it was always disconnecting the calls on its own and I always could not hear the other party speakign to me. one more problem was that alot of my friends kept telling me that my mobile is always switched off while it alwyas showed full signal and it is switched on.
Technocare has shown very bad customer service as after they returned it to me the first time, the mobile started giving me even new problems and the old ones came back again, the touch on the screen started to be so bad, it was so difficult to naviagte from one page / icon to another.
Technocare picked up the mobile for the secoind time and when they returned it they said they changed the board and the battery, howevere, it came back with all the same old problems and on top of that the battery whichj i had never complained and they changed starting wearing off much quicker than it used to be. And what drove me ven crazy was that the SIM card compartment was even damaged as it seems someone tried to open it the worng way.
I contacted HTC Contact Us for their support, but they were even worst, it took them ages to communiacte with them, just like Techncocare and until today i have not recieved a proper customer service, i had to email them repeatidly and I only got to know that my mobile was repaired again June 4th and they tried calling me once but i did not pick up because i was in a meeting and so they just considered they ahve done their part.
IU rceieved call from Technocare telling me they will send me back my mobile as per instructions from HTC COntact Us but i refused to recieve utnil i am conatcted appropriately by HTC and understand what had happened and the update on my mobile. They called me from an unkown number os i can not even return the call this is so frustrating and i have been without my mobile since March 14th, 2013.
Please i need to raise this complaint to a higher level to be investigated in at the least someone repsonsible contact me and understand what is my problem. i have all the correspondance i can share it with you as appropriate.
Thank you
